A Chef handler to cleanup stale Sensu checks by cross-checking the files in your checks directory with the resources from the Chef run.
The Chef docs [1] lay out a pretty simple way to use handlers by leveraging the chef_handler resource. Just ship the chef-handler-sensu-cleaner.rb file to your handlers location and declare a new handler:
cookbook_file "#{node[:chef_handler][:handler_path]}/chef-handler-sensu.rb" do
source 'chef-handler-sensu.rb'
mode 00600
end
chef_handler 'SensuCleaner' do
source "#{node[:chef_handler][:handler_path]}/chef-handler-sensu.rb"
action :enable
end
Obviously make sure to copy the ruby file into the /files/default
directory
of your cookbook as well. Alternatively, install it as a Rubygem and source it that way:
chef_gem 'chef-handler-sensu' do
action :install
end
chef_handler 'SensuCleaner' do
source ::File.join(Gem.all_load_paths.grep(/chef-handler-sensu/).first,
'chef-handler-sensu.rb')
action :enable
end
